    There's nothing worse from a useability standpoint than providing enough similarity to trigger automated behaviour, but then being different enough for that behaviour to have different results.

    So the copy-then-innovate path is fundamentally flawed, because you have to start out by copying 100% faithfully. Gradual evolution from there is very hard on the user too, precisely for the reason stated above.

    On the other hand, if something is /different/ but simply better, users will come. Instead of looking at Windows, read Raskin, and try to attract people who have /vision/ in this area.

    After all, people managed to switch from WordPerfect 5.1 to Word 2.0, not because of Word's similarity, but because it was simply better for painting memos at the time, and that is what people most often do with their word processors.

    The whole win32 layer should have been completely re-implemented, as lightweight services, keeping only the sane parts of the application level API, and shove the rest into a compatibility thing that should be deprecated from day 1. Apple is able to pull that stunt quite well (cf. Carbon).

  6. No offense intended on Can Cell Phones Damage Our Eyes? · · Score: 1

    Of course I understand that the normal high pitched noise you can hear near a TV is just the coil being loose or other stuff moving air, ie. generating ordinary sound. That's a purely auditory phenomenon. I was merely describing the sound/sensation I have had after exposure to some Wi-Fi APs.

    I agree that the photo flash triggers lots of nerve cells and that it's much easier to cause disruption this way. Nerve cells may not ordinarily be very sensitive to RF, but the signal recovery that can be done by massive paralellism (think lofar) is enormous. Also, half a lambda of 2.4GHz fits nicely in your skull -- maximum efficiency wrt. potential and field strength differences.

    I really have the experience of 'raising the noise floor' in the head, if I can use that analogy. Near APs or some operating cellular phones I can't think of as many things at once as I'm used to, and as a programmer, it's essential to cover lots of possibilities and decision trees quickly.

    I'm playing with the possibility of cognitive problems, because around here, there's still in most cases no AP operating near you. If this feeling of only being able to hold one strong thought at a time occurs, and I ask eg. my customer whether there's wireless, most often there is. I also often measure if there's any Wi-Fi around, and a good day is often confirmed by no Wi-Fi around.

    By the way, I didn't mean to paint USians ignorant! I just think they're generally going a bit overboard these days with installing Wi-Fi in every coffee shop, around every park, and those municipal Wi-Fi projects. It has a cool factor to surf the web in impossible places, but generally you prefer a bit of comfort for serious computing.

    But if you consider that a low intensity, 15 Hz flash is enough to give some people epileptic seizures, while they can easily stand the intensity of the continuous sun, then that gives me some reason to suspect that a signal's low frequency envelope and the disturbance that can cause on the oscillating processes that take place in your brain and even in simpler cells is the thing to look out for here.

    Personal experience has made me quite cautious with pulsed broadband microwaves, especially if the pulse frequency is below a few hundred Hz.

  8. Non-thermal effects on NYT on Cell Phone Tower Controversy · · Score: 1

    But I still doubt that there is signficant non-thermal influence on chemical reactions by certain 'matching' microwave photons, the only other reasonable cause of adverse effects. AFAIK all the studies in this area are at least highly disputed.

    I've been wondering about a couple of other interaction modes and would be interested to hear what people more versed in this stuff can say about them.

    1. AM demodulation - if absorbed radio energy in the GHz range varies in a certain period (eg. 100Hz), is there any biological process that may cause a 100Hz signal to be generated in your brain?

    2. potential differences - it's all fine that strong chemical interactions aren't likely, but in case of a wavelength of a few centimeters, the maximum difference in potential (1/2 lambda) will fit inside your skull. In case of 'common' radio applications, it won't be enough for an electroshock, but I wonder if it doesn't raise our 'noise floor'. We evolved in an EM environment that was noisy at times, but mostly quite silent. No persistent 'wide' band screeches, strong AM patterns, or GHz carriers.

    If you think extremely small currents can't be received by coarse synapses, think LOFAR -- you just take an /awful/ lot of them to restore your signal. This is exactly what the brain is good at.

    The reason I'm asking is that NL has just started with DVB-T transmissions on UHF, UMTS at 2.1GHz is getting some users and that this hugely overrated WiFi-revolution has really picked up steam mid 2004 here. Since that time, I've become quite sensitive to some EM generating equipment in terms of 'hearing' extremely high pitched noises and experiencing concentration loss. If I notice I'm struggling for words, and measure if there's a good WiFi signal, more often than not there is (and if I'm not having the problem, more often than not there's no WiFi -- I'm sure as hell staying away from it now).

    The reasoning is: it doesn't ionise, and doesn't cause heat damage, so there's no interaction, not even with a live human brain. I find that reasoning a bit bold, to be honest. Of course the service providers have an interest to keep beating that drum, but that you need to carry the burden of proof if you're worried about health effects is, frankly, not very scientific.

  10. It doesn't need to break DNA itself on The Story Behind Cell Phone Radiation Research · · Score: 1

    You're missing the forest for the trees. That mechanism you introduced as far fetched with 'maybe, maybe' is far less intricate than the immune system.

    In the vast majority of cases, cancer cells are killed by your immune system before they get a chance to develop into tumors. So it only takes an agent to subtly affect your immune system (is a psychological mood subtle enough for you) to allow for an increase in cancer.
    Don't invoke that "doesn't ionize, so doesn't harm" too soon!

    A propos, I think that cancer is vastly overrated as an endpoint in studies about new chemical or physical agent. "If it doesn't cause cancer, it's harmless", seems to be the line of thinking. Ritalin, Seroxat, Prozac don't cause cancer, but I wouldn't dream about taking them if I haven't developed any of the conditions for which they're prescribed.

    What I think is much more important than cancer in the context of the wireless revolution is whether all that electromagnetic noise could raise the noise floor in your brain, killing subtle thoughts, creativity and inspiration.

    It wouldn't surprise me if antennae turn out to be the factory chimneys of the 21st century. We're in a "hooray, we've found an unlimited new toy" stage right now, and it'll probably take a few years before we move to lower power levels, and probably more importantly, more carefully chosen signal envelopes and/or modulation types to avoid interfering with the human brain.

    The brain was constructed before EMC guidelines were in effect, so it may not be all that resilient against interference.

    That attitude "I can't see a mechanism, so it can't be true" is so thoroughly un-scientific, especially if there /are/ scientifically proven routes to cancer other than DNA damage. DNA damage occurs naturally, it also depends on how well you repair it or do away with cells that have gone astray.

    If as a species we only could be saved by God taking away our freedom of choice and reducing us to mere angels, who have no choice but to obey God, then that would be pretty sad, and I for one am rather human, despite all the suffering that occurs due to human actions, than a creature that lacks the unique responsibility that comes with this life.

    So, it appears that Sveasoft, who makes firmware that is derived from GPLed software for Linksys' WRT54G router, has found an interesting way to 'discourage' recipients of their source and binary software from redistributing it -- apparently without violating section 6 of the GPL ('You may not impose any further restrictions on the recipients' exercise of the rights granted herein.').

    Their trick is that in order to receive binary + source prereleases, you need to have a paid subscription with them. That's fine under the GPL of course. However, they say that once you excercise your right to redistribute granted by the GPL, they will terminate your paid subscription, which of course does not revoke any rights to the software you've received (which were given you under a GPL license after all), but it does make it impossible to get /future/ pre-releases without subscribing again, for a certain fee.

    They seem to think that because the 'punishment' for excercising certain rights granted by the GPL does not place any additional restrictions on /the particular version of the software you received/, it does not trigger GPL section 6.

    Indeed. A continuous wave or narrowband FM signal at 2.4 GHz shouldn't do much harm other than warming things a little. However, when you start sending all sorts of pulse patterns it becomes a whole different matter.

If such droplets are enclosed in something else, pressure will vary with the same pulse rithm. Perhaps it's even possible to make a small cavity resonate, I don't know.

    The problem is that almost all research into non-ionizing radiation looks only at the amount of energy transferred, and the risks associated with absorbing that energy, as if it's diffuse and applied continuously. Indeed, when evaluated this way, any electromagnetic energy with frequencies below X-ray will have very manageable risks.

The tradeoff might have been worth it, but with the current terms and in its current DMCA/EUCD form, I'm personally convinced that doesn't hold anymore.

    IMHO we need to move to a scheme where the interested audience pays once, before the work is published. The audience invests based on reputation and bears the risk. After publishing, the author releases all control.

    A system where an artist could put up an auction saying, "I need 750,000 EUR to make this production. Collection of funds ends in three months. If the required amount hasn't been reached, everyone will be payed back minus 5% to cover auction costs and other expenses, guaranteed by bank XYZ. Previous works are .., .., .., .., auctioned for .., .., and .., resp." would be ideal. Couple this with a good search engine to allow public and artist to find each other and I think music, games, film, and other products of pure information could thrive without copyrights.

    The only thing you'd miss as an artist is the income from surprise hits. You'll only be able to cash in on your next production.
